I've managed to get to 1.8.2sr1 without an issue from 1.8.1
However, trying to get from 1.8.2sr1 to 2.0.0 has been difficult.
I exported my 1.8.1 data to data181.sql and ran the "migrate" option since I'm testing the process on a new server.
This got me to 1.8.2sr1.
I exported my 1.8.2sr1 data to data182.sql and proceeded several times now
to attempt the 2.0.0 install. After choosing to migrate the data182.sql, I get only a blank page after the migrate option starts|attempts its function.
I enabled $_CONF['rootdebug'] = true;
and have this message:
PHP Formatted CodeIf
this is a production website you must disable this option once you have resolved any issues you are investigating.
256 - 1054:
Unknown column 'whos_online'
in 'field list' @ /var/
php line 279
# Function File Line

string(120) "UPDATE gl_sessions SET start_time = 1391725984, whos_online = 1 WHERE (md5_sess_id = '3eab377cf7754a72fd58153b26248c36')"
Which if odd since I don't even use the "who's online" feature/block on my 1.8.1 site.
I deleted the block from my data182 "site" and re-exported the db to data182.sql and tried the upgrade to 2.0.0 again with the same result
cache is cleared.
What should I do to fix this?
Edit: I deleted the who's online block from my 1.8.2sr1 site and tried migrate again, no likey.
